## What the Chassis To RC API does

Chassis To RC resolves a vehicle identification number to its registration record, returning the registration number and associated vehicle details.

The chassis number is stamped into the vehicle itself and cannot be swapped like a number plate. That makes it the identifier to trust when you are verifying a physical vehicle rather than a document.

## Where teams use the Chassis To RC API

1.  Identifying a vehicle during a used-vehicle inspection
    
2.  Verifying a vehicle where the plate is missing or suspect
    
3.  Cross-checking chassis against the claimed registration
    
4.  Investigating a vehicle in an insurance claim
    

## Frequently Asked Questions (FAQs)

Where is the chassis number found?

Stamped on the vehicle body, and printed on the RC and insurance documents. Reading it from the vehicle is the point when you suspect the paperwork.

How does this differ from Chassis To RC Details?

Both start from a chassis number. Chassis To RC Details returns a fuller vehicle record; use it when you need more than the registration mapping.

Can I search by engine number instead?

Yes. Engine to RC Details resolves a vehicle from its engine number.
